Silicones for Building Protection

Why building materials are in need for a protective agent

Typical damages carried in by the water and affecting the life of a

building material and its aesthetic

• Chemical corrosion (acid rain attaching the material)

• Frost damage and freeze/thaw damage by road salts (cracks)

• Efflorescence and salt stains

• Fungal and lichens growth

• Dirty pick up

• Rust stain (in reinforced concrete)

Repairing is typically more expensive than preventing

Why choose Silicone impregnating agents

• Silicone based water-repellents are the most effective

protective agents for building materials:

• Strong chemical links with the mineral surfaces

• Long lasting resin network repellent to the liquid

water but permeable to the water vapor.

• Not film forming thus pores are not closed and

material can “breathe”

• UV resistant hence assuring a long life of the

protective treatment

Why choose Silicone impregnating agentsPrinciple of water repellencyThe alkyl groups protects the

substrate like umbrellas

Why choose Silicone impregnating agents

Properties:

• Good water repellence

• Excellent water vapour permeability

• Good resistance to alkalis

• Good penetration depth and durability

• Unchanged appearance of the substrate

• Stop growth microroganism (left) and efflorescences (right)

For the most common silicone resins R might be Methyl or Phenyl group.

• Methyl Groups (Me) bring water repellency, release, incompatibility with

organic products, hardness but also fragility

• Phenyl Groups (ɸ) bring thermal resistance, Thermoplasticity, flexibility,

compatibility with organic products, chemical resistance

A resin contains reactive functions (silanol or alkoxy groups) that react to

build up the network and increase the molecular weight.

Alone as a resin: Room temperature moisture curing

(need catalyst/curing agent) coatings (short tack dry

time, high hardness and excellent water-repellency,

high temperature paints up to 600-650°C, auto body

coating, floor coatings etc)

As Organic Resin Modifier (especially water based)

Add typical silicones features (weatherability, water-

repellency, heat resistance) to those belonging to

organic polymer. Major application:

- Acrylic (construction material coatings)

- Polyester (industrial, high temp operating appliances)

- Epoxy (anti stain, anti corrosive paints)

- Alkyd (storage tankers, external structures)

• Silicone resins are easier to coat (one step cycle) than silicone elastomers

as well as PTFE (multi step process).

• Number of baking can be extended provided an accurate pre-treatment

• Re-coating is also less expensive than for the other technologies
